The 1998 Pep Boys Indy Racing League was one of relative stability compared to the previous two seasons. For the first time the season consisted of a single and complete spring, summer, and fall like all other motorsports. 15 drivers completed the entire 11 race schedule, twice as many as the previous season. It was also the first complete season for the new Riley & Scott chassis, though it proved unpopular due to its late introduction. A. J. Foyt Enterprises drivers captured 4 wins, the Indy 500 pole, and the championship, arguably the most successful year in the team's history.
